Current Bar

elmex Current Bars are made of electrolytic copper or a high quality copper alloy and tin plated with higher than usual plating thickness, to maintain the contact surface free from atmospheric corrosion. Nickel under-coat prevents zinc migration in case of copper alloy current bars. 

Special features of elmex current bars are the provision of longitudinal serrations to grip the conductor while tightening, and cut into thin oxide film of conductor. The contact resistance remains very low, once the conductor is firmly clamped.
